The Tomb is set, well, in a tomb containing the sarcophagus of the father of Anthony, the principal character. Having one setting enables a continuous flow of the story. When alone, Anthony often speaks in a meditative and contemplative fashion in an attempt to discern what God wants or expects. On the other hand, there are times when visually he is alone, but he perceives and confronts the demons that inhabit this cave. He names and rebukes them, each, in turn. Even when other characters, portrayed by the same actor, come in to converse with him about what is going on in the outside world, this world within the cave is only reinforced to the audience.
What I didn't like
The position of the actor portraying the bishop, so close to Anthony, made the realization that he was outside the cave while Anthony was inside a bit jarring.
My overall impression
How does one tell a story from the perspective of a historical figure? Especially if the story is about a hermitic life, which means that there are many private moments that must be imagined or extrapolated from other sources? This piece accomplishes that.
